Genes affected

EPX (HGNC:3423): (eosinophil peroxidase) This gene is a member of the peroxidase gene family and is expressed in eosinophils. The encoded preproprotein is proteolytically processed into covalently attached heavy and light chains to form the mature enzyme, which functions as an oxidant. The enzyme is released at sites of parasitic infection or allergen stimulation to mediate lysis of protozoa or parasitic worms. The gene is found in a gene cluster with other peroxidase genes on chromosome 17. Mutations in this gene result in eosinophil peroxidase deficiency. [provided by RefSeq, Feb 2016]

ACMG classification

Our verdict: Benign. The variant received -14 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0073302686).
• BP6: Variant 17-58193077-G-A is Benign according to our data. Variant chr17-58193077-G-A is described in ClinVar as [Benign]. Clinvar id is 782915.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.00112 (169/151430) while in subpopulation EAS AF = 0.0216 (111/5136). AF 95% confidence interval is 0.0184. There are 4 homozygotes in GnomAd4. There are 81 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position FAILED quality control check.
• BS2: High Homozygotes in GnomAd4 at 4 AR gene
